No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/fdsn_availability for the schema, then POST the same URL with its arguments for the data.

“Where can I download waveform data for station IU ANMO in September 2026?” — which FDSN data centres actually hold seismic waveform data for a given network/station/channel and time window, from the EarthScope federated catalogue. Returns each data centre that holds matching data, its dataselect and station service URLs, and the exact network/station/location/channel/time rows it can serve. This is the “is the data there, and from whom” question — the waveform bytes themselves are fetched from the returned dataselect URL, not from here.

Parameters

Name	Type	Required	Description
`network`	string	no	FDSN network code, e.g. “IU”. Wildcards allowed.
`station`	string	no	Station code, e.g. “ANMO”. Wildcards allowed.
`channel`	string	no	Channel code, e.g. “BHZ” or “BH” (default ””).
`location`	string	no	Location code, e.g. “00”. Default any.
`starttime`	string	no	Window start, YYYY-MM-DD or ISO 8601 (default: 7 days ago).
`endtime`	string	no	Window end, YYYY-MM-DD or ISO 8601 (default: today).
`limit`	number	no	Max channel rows to return per data centre (default 50, max 500).
